Izinjongo: Ukuthuthukisa inoveli ye-polypropylene eyinhlanganisela yezinto ezinomsebenzi we-antimicrobial ngokungeza izinhlobo ezahlukene ze-nanoparticles yethusi.

Izindlela nemiphumela: Insimbi yethusi (i-CuP) ne-copper oxide nanoparticles (CuOP) yashumekwa ku-matrix ye-polypropylene (PP).Lezi zinhlanganisela ziveza ukuziphatha okunamandla kwe-antimicrobial ngokumelene ne-E. coli okuncike esikhathini sokuxhumana phakathi kwesampula nebhaktheriya.Ngemva kwamahora angu-4 nje okuxhumana, lawa masampuli ayakwazi ukubulala ngaphezu kwama-95% amagciwane.Ama-CuOP fillers asebenza kangcono kakhulu ekuqedeni amagciwane kune-CuP fillers, okubonisa ukuthi impahla elwa namagciwane incike kakhulu ohlotsheni lwezinhlayiya zethusi.U-Cu²⁺ okhululwe kunqwaba yenhlanganisela unesibopho salokhu kuziphatha.Ngaphezu kwalokho, izinhlanganisela ze-PP/CuOP zethula izinga eliphezulu lokukhululwa kunezinhlanganisela ze-PP/CuP ngesikhathi esifushane, zichaza ukuthambekela kwe-antimicrobial.

Iziphetho: Izinhlanganisela ze-polypropylene ezisuselwe ku-nanoparticles yethusi zingabulala amagciwane e-E. coli kuye ngezinga lokukhululwa le-Cu²⁺ kusuka kunqwaba yezinto.I-CuOP isebenza kakhulu njengesigcwalisi se-antimicrobial kune-CuP.

Ukubaluleka nomthelela wocwaningo: Okutholakele kwethu kuvula ukusetshenziswa kwenoveli yalezi zinto zepulasitiki zokudiliva i-ion-copper ezisekelwe ku-PP ezinama-nanoparticles ethusi ashumekiwe anamandla amakhulu njengama-antimicrobial agents.
